Diagram Ref No 2

Also described as a front stabiliser bar mounting bush or sway bar bearing, this component forms part of the mounting arrangement that holds the anti-roll bar in its correct position.

The anti-roll bar is an important element of the suspension system. It helps reduce excessive body roll during cornering by resisting differences in suspension movement between the left and right wheels.

For the anti-roll bar to work correctly, it must remain properly located within its mounting points while accommodating the controlled movement associated with suspension travel.

The Porsche bearing bracket 99134379207 provides this support, helping maintain the intended position of the front stabiliser bar and reducing unwanted movement within the mounting assembly.

On vehicles such as the Porsche 911 Carrera and mid-engined Boxster and Cayman, accurate suspension response is central to the driving experience.

Even relatively small suspension mounting components can influence the way loads are transmitted through the chassis.

Over time, anti-roll bar mounting bushes can deteriorate through repeated suspension movement, temperature changes, road contamination and general ageing.

Worn mounting material may develop cracks, compression or excessive clearance around the stabiliser bar.

When this happens, the anti-roll bar can move more than intended, potentially causing knocking, rattling or creaking noises from the front suspension.

Severe deterioration may also affect the consistency of the anti-roll bar's response during cornering.

Replacing a defective bearing bracket with Genuine Porsche part number 99134379207 helps restore the correct factory mounting arrangement, maintaining the original suspension characteristics.

This part is particularly suitable for front suspension repairs, maintenance of noisy stabiliser bar mounts and replacement of deteriorated anti-roll bar bushes.

What This Product Does:
The bearing bracket forms part of the mounting arrangement that supports the front anti-roll bar.

Its main functions include:

  • Supports the Front Anti-Roll Bar: Keeps the stabiliser bar correctly positioned within the suspension.
  • Maintains Bar Alignment: Helps prevent excessive movement or displacement.
  • Cushions Suspension Movement: Provides an interface between the anti-roll bar and its mounting arrangement.
  • Helps Reduce Noise and Vibration: Limits unwanted rattling or contact caused by excessive movement.
  • Supports Body Roll Control: Allows the existing anti-roll bar to perform its intended function during cornering.
  • Maintains Suspension Precision: Helps preserve consistent stabiliser bar response.
  • Accommodates Controlled Movement: Allows the necessary movement of the anti-roll bar during suspension travel.
  • Protects Adjacent Components: Reduces unwanted loading caused by a loose or incorrectly located bar.
  • Restores Factory Fitment: Replaces a worn mounting component without changing the suspension specification.

Symptoms Of Wear Or Failure:
The front anti-roll bar mounting is exposed to constant mechanical loading during vehicle operation.

Although it is not normally replaced at a fixed service interval, deterioration may occur with age and mileage.

Typical symptoms:

  • Clunking over speed bumps.
  • Knocking on rough road surfaces.
  • Rattling during low-speed driving.
  • Noise when entering driveways.
  • Sounds that become more noticeable when one front wheel moves independently of the other.
  • Squeaking over bumps.
  • Creaking during cornering.
  • Noise as the suspension compresses.
  • Sounds from the front anti-roll bar mounting area.
  • Visible cracks.
  • Splitting around the mounting.
  • Hardened or deteriorated rubber.
  • Permanent compression.
  • Damaged edges or distorted mounting surfaces.
  • Visible movement at the mounting point.
  • Excessive clearance around the bar.
  • Unusual play during inspection.
  • Wear marks around the stabiliser bar.
  • Incorrect bar positioning.

Why Replacement Matters:
Replacing a defective anti-roll bar bearing bracket helps restore the correct positioning and support of the front stabiliser bar.

Although relatively small, the component contributes to the consistency and refinement of the suspension system.

  • Restores Correct Stabiliser Support: Maintains the anti-roll bar in its intended mounting position.
  • Reduces Suspension Noise: Can eliminate knocking caused by excessive movement.
  • Helps Prevent Creaking: Replaces damaged or deteriorated mounting material.
  • Supports Predictable Handling: Maintains the original anti-roll bar function.
  • Reduces Unwanted Bar Movement: Helps restore correct mounting clearance.
  • Protects Adjacent Components: Minimises unnecessary contact and movement.
  • Maintains Factory Suspension Geometry: Preserves the original Porsche mounting arrangement.
  • Improves Suspension Refinement: Helps reduce vibration-related noise.
  • Suitable for Chassis Maintenance: Provides a replacement during front anti-roll bar servicing.
  • Genuine Porsche Quality: Uses the original equipment component specified for compatible vehicles.

Product Information
Lateral support clamp anti roll bar. 

Anti-Roll Bars (ARB’s) play an important role in a vehicle’s suspension system, helping to reduce body roll by transferring cornering load from one side of a vehicle to the other.

Often mounted to the vehicle’s chassis with rubber bushes, these bushes ensure the bar works as intended. To prevent the anti-roll bar from moving laterally within its mounts when turning, OE manufacturers will either bond the bushes to the bar, add dead-stops to the bar itself, or rely solely on the clamping pressure of the rubber.

But what happens when those bushes wear and need to be replaced? Often anti-roll bars with bonded bushes come as a costly complete assembly, so the alternative is to fit a more cost-effective unbonded polyurethane replacement, like the many we offer.

In most cases, friction from the bush will prevent any side-to-side bar movement. Still, when turning aggressively or cornering at higher speeds, a laterally shifting anti-roll bar decreases the efficiency and effectiveness of the bar, changing the dynamics of your suspension system in unpredictable ways. It also poses the risk of the bar fouling on other areas of the vehicle or suspension system.
